everytime I have change my spark plugs, they indicate that my engine is running hot. I have my fan hooked up to turn on w/ my engine. And my car never overheats, so if anyone has any info on it please help.

 

What do you mean by "running hot"? If they are clean and dry, why worry? Do they have metal specs from engine parts on them? Lastly, you say "every time I change my plugs". How often do you do it? Maybe they're just new looking since you change them so often. If you're not getting detonation, or 10 miles to the gallon, I wouldn't worry if it runs good.
